average speed = total distance÷total time
average speed = (50+40+30)/10+10+10
= 120/30
= 4 m/s

Answer:
The average speed of a boy will be 4 m/ sec
Explanation:
we have given in the question as
A boy first covers 50 m distance, in time 10 seconds
and after that he travels more and cover more 40m in time 10 seconds and again he travels more 30 m in 10 seconds time. We Need to calculate the average speed of a boy.
We know that the formula of average speed is
Average speed= Total distance travelled / total Time taken
Now put the above values in the formula we get.
50+40+30/10+10+10
=120/30
=4
hence the average speed of a boy is 4 m/sec.
which is the required answer.
